Microchip Technology's MCP120T-460I/TT Voltage Supervisor

The MCP120T-460I/TT is a highly efficient voltage supervisory device designed to keep microcontroller-based systems within safe voltage operating conditions. Manufactured by Microchip Technology, a leader in microcontroller, mixed-signal, analog, and Flash-IP solutions, this voltage supervisor is an essential component for reliable system operation. It is particularly suitable for use in automotive, industrial, and consumer applications where precise monitoring of system voltage is critical.

This device is part of the MCP120 series and is designed to assert a reset signal whenever the V<sub>CC voltage drops below the factory programmed threshold of 4.60V. The reset output remains asserted until V<sub>CC rises above the reset voltage threshold and for a period of time after that, ensuring the system has adequate time to stabilize. This timing is critical for systems that require a reliable reset signal to recover from brown-out conditions.

Key Features:

• Precision Voltage Monitoring: The MCP120T-460I/TT offers a precise voltage threshold of 4.60V, ensuring accurate monitoring and control of system voltage.
• Low Power Consumption: With a typical supply current of just 1 µA, this device is highly energy-efficient, making it ideal for battery-powered applications.
• High Accuracy: The voltage threshold accuracy is ±1.5%, which provides a reliable reset signal under varying conditions.
• Operating Temperature Range: The device operates within an industrial temperature range of -40°C to +85°C, making it suitable for harsh environments.
• Reset Time Delay: It features a built-in delay time of 350 ms (minimum), which allows the connected microcontroller or processor to properly initialize during power-up.
• Compact SOT-23 Packaging: The MCP120T-460I/TT comes in a small 3-lead SOT-23 package, ideal for space-constrained applications.

Overall, the MCP120T-460I/TT voltage supervisor from Microchip Technology is a robust solution for systems that require reliable monitoring and control of their supply voltage. Its low power consumption and high accuracy make it an excellent choice for designers looking to enhance system stability and protection against power supply anomalies.
